Theories on the History of Science as Social Constructs Essay

Theories on the History of Science as Social Constructs - Essay Example l description of Hess’s concepts related to the cultural construction of science and technology, this paper moves towards a comparison between the theories of Carolyn Merchant and Hess. Both of them have their own ideas related to science, technology and nature. Merchant takes a feminist stance in her description of science and technology. At the end, a conclusion is given that summarizes the overall paper. T.S. Kuhn is his book, â€Å"The Structure of Scientific Revolutions†, evaluates the history of Science. Kuhn illustrates that science has not developed from accretion of factual information but from continuous transforming situations and probabilities for the people related to scientific disciplines (Polsby, 1998). For Kuhn, science that was prevalent in different eras of history was an output of the factors at that time (Polsby, 1998). Kuhn divided the history of science in three phases. In the first phase, there was no agreement on a single theory and people differ from each other in terms of suggested theories due to which, the theories of this phase were left deficient (Kuhn, 1962). Second phase saw some acceptance on theories and there was proper experimentation and analysis (Kuhn, 1962). Kuhn regards the third phase of science as innovatory and revolutionary (Kuhn, 1962). According to Kuhn, science moves between these phases to get some results (Kuhn, 1962). The movie, â€Å"Mindwalk† directed by Bernt Amadeus Capra introduces three characters who are involved in a correspondence. First one is a politician; second one is a scientist while the third one is a poet. Each of them has a diverse viewpoint and sees the world differently. The movie is based on Kuhn ideas that are linked to the discovery of new concepts in scientific field. The movie illustrates that people should not rely on old discoveries and theories, they should revolutionize and should move towards new grounds. As Kuhn has explained that, every scientific development has three phases,

Changing Character of Alien Immigration in Early Modern Period Essay

Changing Character of Alien Immigration in Early Modern Period - Essay Example It is evidently clear from the discussion that the most powerful of European powers ventured into the immigration spree during the Early Modern Period to show specific interests. Nearly through the entire 16th century, the most explorative and dominant figure of alien immigration into the Americas was undoubtedly Spain. Since the turn of the Century, Spanish interests in the New World were perhaps one of the most organized and resolute. As early as 1513, sections of the continent had been identified for settlement by the Spanish explorers as led by Ponce De Leon. Florida was among the settlement areas identified by De Leon, paving way for similar incursions into other American territories by the Spanish. In as much time, Cazabeza de Vaca and his crew had discovered Arizona, New Mexico and Texas in a similar adventure. Discovery and navigation of main American rivers such as Colorado and Mississippi were nigh as exploration continued into the 1500s, soon making it possible to take ove r Florida and California. In the meantime, other explorer countries in Europe were preparing to compete with Spain in the venture and English explorers sooner came on board. Despite the fact that much of the discoveries leading to the immigration of the Europeans were by chance, they took complete advantage of the discoveries and eventually occupied the New World. The English explorers, for instance, were in search of routes to the Indies, making the stumble-upon impact good to their interest in overseas territories. Virginia was taken over in 1607 by the British. The French got interested in the immigration and settlement in 1608 through the assistance of Samuel Champlain in form of identifying and taking over Quebec. By 1670s, interests of expansion of the overseas territory by the French led to exploration and takeover of Louisiana.

The establishment of America was long and controversial, but the Research Paper

The establishment of America was long and controversial, but the nation thrived in justice and liberty - Research Paper Example It discusses in detail the urge and the constant struggle of the nation to attain liberty and justice extracting ideas and information from the Voice of Freedom by Eric Foner. The majority of the individuals living in the United States were mainly the farmers and Native Americans (Indians). However, during the time of the exploration most of the European nations migrated to America for trade. The war of the independence initially begins when the different colonies that established in the south and North America because of the migration caused cultural diversity. The demands of the diverse group living in America transformed the meaning of freedom. These groups on their own strived to attain justice and fought for their rights. The peasants fought for their lands and rights, gender discriminations and religious freedom. It is evident during the American Revolution that the demands of equality among the people of America were often question. The peasant and slaves in America were recognized as inferior and had lower socio-economic status in the society. The difference between the privilege of the servants and peasants was embarked to be one of the major iss ues due to which the people of America strived for justice and independence. Hence, â€Å"The liberating Indentured Servant (1784)† was enacted that provided status for the slaves and servants in American Society. Eric states, "a group of respectable New Yorkers proposed to liberate the ship of the African slaves that were brought to America" (Foner 104). These free slaves were provided with a respectable and social status in the society so that they can enjoy their freedom to practice their rights. Previously, Virginia did not have a stable family structure because of the strict rules for the servants in the tobacco field. Browne (1644) States that Virginia remained to be a society with the high number of single men, widows and orphans rather than

Business Law Essay Example | Topics and Well Written Essays - 1000 words - 2

Business Law - Essay Example The primary concern of the questioner is whether his concern can be referred to the court. The other two concerns are: 1. Position of the concerned court with respect to end-of service gratuity for the previous period of the visa. 2. Salary difference of the actual received and mentioned in the labour contract. Response: Al Shaiba clarified about the right of questioner that he has full right to get compensation based on his actual employment duration which is three years. Regarding the salary difference, Labour Law calculates the compensation based on the current salary drawn by the employee. Therefore, both the concerns addressed clarify that the employee shall get his case referred under the concern court through the Ministry of Labour. Query#2: Gratuity Calculation The questioner worked in a company under unlimited contract for one year before tendering his resignation. Questioner has two queries: 1. The end of service gratuity was calculated on the basis of 21 days salary. 2. If the questioner is legally entitled for a return ticket to his home country as the contract was signed in the home country. Response: Al Shaiba gave the reference of Article No 137 of the Federal Labour Law No.8 of 1980. This article clarifies the doubt of the respondent. The article states, "Where a worker under an indefinite term contract abandons his work at his own initiative after a con ­tinuous service of not less than one year and not more than three years, he shall be entitled to one-third of the severance pay provided for in the preceding article. Such a worker shall be entitled to two thirds of the said severance pay if his continuous service exceeds three years up to five years and to the full severance pay if it exceeds five years". The second doubt is clarified that the employee is entitled to get the return tickets to home provided he returns back to home country and does not work with a new employer. Query 3: Arbitrary Dismissal This is a case of dismissal of an emp loyee who was working for his company from more than two years. The nature of the contract was for unlimited period. The employee received dismissal due to his absence from work for five consecutive days without excuse, 6th day he was present at work but again 7th and 8th day he went absent. The dismissal was justified under pursuant of the Article n. 120 (Labour Law) and employee was explained that he was not entitled to end-to service gratuity even after producing medical report for the absence period. The queries were: 1. Questioner wanted to know the Article 120 in detail. 2. Questioner wanted to clarify what should he do if the dismissal is not in conformity of the Article no.120 of the Labour Law 3. If there is no conformity; could he get reinstated by his company under legal obligation of Ministry of Labour/Competent court? Answer: The article No.120 of the Federal Labour Law No.8 of 1980 is as follows: "An employer may dismiss a work ­er without notice if and only if the w orker: 1. Assumes a false identity or na ­tionality or submits forged certificates or documents; 2. Is engaged on probation and is dismissed during or at the end of the probationary period; 3. Commits a fault resulting in sub ­stantial material loss to the employ ­er, provided that the latter notifies the labour department of the inci ­dent within 48 hours of his becoming aware of its occurrence; 4. Disobeys instructions on

Child Development Essay Example | Topics and Well Written Essays - 2750 words

Child Development - Essay Example The book covers the general theories that explain include development process outlined in relation to the age of a child, the aspects that one has to look closely in child’s development process, the main problems that may be hinder a child’s development, and the required environment to ensure healthy child development process. The booklet will be a worthy companion for all beginners in childcare or child development studies. 2.0 Major Child Development Theories 2.1 Piaget Cognitive Development Theory Jean Piaget was a Swiss theorist who died in 1984. Piaget believed that children’s thinking pass through four systematic separate stages with qualitative changes in each stage (Shaffer & Kipp 2010, 294). According to Piaget a stimulating environment and maturation are the most important aspect in this stage. As the child begins to explore and make connections with the physical world many changes occur in the baby and start to acquire skills and knowledge about their environment. Below are the various stages of a child’s development according to Piaget theory as explained by Shaffer & Kipp (2010, 294). Sensory period (0- 2 years). The child attains significant gains in its thinking as they progress. Children at this stage mostly use motor and physical skills and senses in exploring their worlds, to enhance cognitive development. Pre operation stage 2 to 7 years. Children become less reliant on senses and physical exploration. They become illogical thinkers and have inability to conserve their memory. Concrete Operations 7 to 12 years. Children in this stage develop more elaborate logical thinking, but still need concrete materials to reach a logical conclusion. This explains that children will require blocks while solving math problems. Formal operation (12 years... This report stresses that child development theories explain that a child’s development has to be holistic, which calls for attention in all aspects of a child’s growth and development. A child has to develop mentally, intellectually, emotionally, cognitively, spiritually, physically, and any other attributes that make them whole and healthy. The family setting and the society are the single most important schools for children. The author of the paper declares that the child struggles to put in place their thoughts, they achieve better learning and development and develop increased confidence levels compared to those supported by their instructors. Piaget in his child development theory illustrates factors that have to be observed in ensuring a holistic child development. This paper makes a conclusion that Children learn first from their parents and the pope around them before interacting with the outer worlds, implying their future life depends on their immediate family and the concepts learned. To ensure an effective learning process, there is need to put in place effective measurement approaches that would portray the progress of a child in their holistic development at home and at school. This would indicate the learning progress of each child and help in identifying children requiring special attention. Therefore, a child’s learning process is essential in impacting the required skills, morals, values and qualities that guarantee a better life in future.

Marketing research Exploring University of Leicester Students' Perception of Healthy Eating and Food Consumption - Essay Example Social Factors 11 3. Consumption Pattern 12 3.1. Involve In Purchasing 12 3.2. Intake of Vegetables and Fruits 12 3.3. Fat Intake 13 3.4. Intake of Fish and Meat 13 3.5 Consumption of Organic Food 13 References 15 Bibliography 19 Appendix 20 Evaluation of Research Design 1. Research Paradigm The research paradigm selected for this study has been interpretive. The interpretive research is chosen owing to different reasons. One of the primary reasons behind its selection is that this approach, unlike positivist approach deems that reality and the individual who observes it cannot be distinguished. On the other hand, the positivist approach believes that the reality is separate from the individual who observes it. The positivist approach is often blamed for its dualistic nature. Interpretative approach is also ascertained to provide an in-depth understanding of the complex world of human experience from their beliefs and perspectives. This approach is further consistent with the constru ction of the social world characterised by the interaction between the researcher and the participants (Andrade, 2009). Hence, the rationale behind selecting interpretive approach is that the study has aimed at attaining opinions regarding the healthy eating and food consumption habit. In this context, the opinions and beliefs cannot be quantified or measured, thus exploratory research has been chosen for this study. The exploratory research facilitates in drawing valuable insights regarding concept, people or any particular situation (Maxwell, 2008). Correspondingly, this study has intended at ascertaining deep insights regarding the participants’ perception on healthy eating and food consumption. While on the other hand, conclusive research particularly involves obtaining and analysing specific data to address particular specific questions (Dr. Nancy D. Albers-Miller, n.d.). Furthermore, inductive research has been adopted in this research study. Unlike deductive research, inductive research involves generalising the observations such as the factors that motivate participants to purchase and consume certain specific food items, which is not feasible with the use of deductive method (University of Pretoria, n.d.). Secondary research had been initially conducted in order to comprehend that further research is required. Moreover, secondary research had been undertaken as it was convenient to identify the known factor with the use of secondary sources. The qualitative research was conducted as the tool for primary research (Church, 2001). The qualitative research was selected in order to gain reliable understanding regarding the behaviour of the participants for uncovering the motivations behind purchasing and consuming certain categories of food items (Roller, 2011). At the same time, ad-hoc research approach was adopted in this study as this study involved identifying certain specific problem that was hard to generalise. While longitudinal approach was omitted as this approach requires longer time as well as it is more complicated and expensive in nature (Yee & Niemeier, 1996). 2. Data Collection Methods Data collection is an important procedure for any research in order to ensure the validity and reliability of the research study. It is thus crucial to select the most appropriate method of data collection. Correspondingly, focus group has been used in this study. The focus group is adopted so that more in-depth understanding regarding the perceptions, attitudes, beliefs and experiences could be

A Brief History of the Hybrid Vehicle Essay Example for Free

A Brief History of the Hybrid Vehicle Essay First built in the early 1900s by inventors tinkering with combinations of the electric motor and the gasoline engine, hybrid vehicles were dropped when gasoline-fueled vehicles became more reliable and easier to start, and gasoline fuel more readily available. Research and development of hybrid vehicles was revived by concern about oil dependency in the1970s and about air pollution in the late 1980s. A number of hybrid vehicles have been built and tested since 1980. Some of these vehicles have impressed analysts with their performance and low levels of exhaust and petroleum consumption. Interest in hybrid vehicles jumped in late 1993 with the announcement of funding for two major collaborations. The US Department of Energy signed a five-year, $138 million development agreement with General Motors and a $122 million agreement with Ford to design and build preproduction hybrid prototypes that could be marketed in less than 10 years. [1] All these were done because hybrid electric vehicles are expected to be the future of vehicles worldwide. Definition One considers a vehicle to be a hybrid when it combines two or more sources of power. For example, a mo-ped (a motorized pedal bike) is a hybrid because it combines the power of a gasoline engine with the pedal power of its rider. Similarly, the gasoline-electric hybrid car is a combination of both an electric car and a gasoline-powered one. That is, it makes use of both electricity and gasoline to provide the energy to turn the wheels of the car. Figure 1 shows a gas-powered car. [2] Components Of A Gasoline Powered Car The 4-cylinder engine converts gasoline into motion so that the car can move. The easiest way it does this is to burn the gasoline inside the engine. Therefore is acts as an internal combustion engine i. e. combustion takes place internally. Gasoline powered car engines typically have over 100 horsepower and operate at speeds up to 8000 RPM. The fuel tank stores and supplies gasoline to the engine. It can typically store enough fuel to provide the engine with energy capable of moving the car through a distance of 300 miles or more. Figure 2 below shows an electric car, which has a set of batteries that provides electricity to an electric motor. The motor turns a transmission, and the transmission turns the wheels. [3] Components Of An Electric Car The batteries store and provide energy to the electric motor in an electric car just as the fuel tank does for the engine in a gasoline powered car. It usually gives the car a range of 50 100 miles which is much less than that typically provided by a fuel tank (300 miles). The electric motor is the device that provides motion in an electric car. It converts the energy it receives from the batteries into motion which is used to turn a transmission which then in turn rotates the wheels. It is able to spin up to 15000 RPM and has up to 100 kW of power. Since this motion is connected to the transmission, the transmission also spins the wheel up to this rate. Thus, electric cars would tend to move faster than gasoline powered cars. Components Common To Both The Electric Car And The Gasoline Powered Car The transmission is the device that does the actual turning of the wheel in both cars. There are several ways of combining the two sources of power found in a hybrid car. The Parallel Hybrid Car: This has a fuel tank which supplies gasoline to the engine. In addition, it has a set of batteries that supplies power to an electric motor. Both the engine and the engine motor can turn the transmission at the same time and the transmission then turns the wheels. Figure 3 shows a typical parallel hybrid. The fuel tank and gas engine connect to the transmission. The batteries and electric motor also connect to the transmission independently. As a result, in a parallel hybrid, both the electric motor and the gas engine can provide propulsion power. The Series Hybrid Car: The gasoline engine in this car turns a generator and the generator can either charge the batteries or power an electric motor that drives the transmission. Thus the gasoline engine never directly powers the vehicle. All of the components form a line that eventually connects with the transmission. [4] Hybrid Components Gasoline engine The hybrid car has a gasoline engine much like the one you will find on most cars. However, the engine on a hybrid is smaller and uses advanced technologies to reduce emissions and increase efficiency. The engine turns the generator. It is not able to power the car directly. Fuel tank The fuel tank in a hybrid is the energy storage device for the gasoline engine. Gasoline has a much higher energy density than batteries do. For example, it takes about 1,000 pounds of batteries to store as much energy as 1 gallon (7 pounds) of gasoline. Electric motor The electric motor on a hybrid car is very sophisticated. Advanced electronics allow it to act as a motor as well as a generator. For example, when it needs to, it can draw energy from the batteries to accelerate the car. But acting as a generator, it can slow the car down and return energy to the batteries. Generator The generator is similar to an electric motor, but it acts only to produce electrical power. It is used mostly on series hybrids. It is where the gas engines power gets converted to electrical power to drive the motor or charge the batteries. Batteries The batteries in a hybrid car are the energy storage device for the electric motor. Unlike the gasoline in the fuel tank, which can only power the gasoline engine, the electric motor on a hybrid car can put energy into the batteries as well as draw energy from them. They can store energy recovered from braking or generated by the motor. Transmission The transmission on a hybrid car performs the same basic function as the transmission on a conventional car i.e. turns the wheels. The motor can spin fast enough so that the transmission needs only one gear. Some hybrids, like the Honda Insight, have conventional transmissions. Others, like the Toyota Prius, have radically different ones like the CVT. CVT stands for Continuously Variable Transmission. It is used to vary the transmission ratio in vehicles continuously. The way CVT works depends on the type: Friction CVTs vary the radius of the contact point between two rotating objects, thus the tangential velocity; Hydrostatic CVTs vary the fluid flow with variable displacement pumps into hydrostatic motors; Ratcheting CVTs vary the stroke of a reciprocating motion, which is connected to a free-wheel, resulting unidirectional rotation. Image courtesy DaimlerChrysler The Mercedes-Benz M-Class HYPER a hybrid concept vehicle[5] Reasons For The Introduction Of Hybrid Electric Vehicles To reduce tailpipe emissions: Gasoline cars are a major source of these emissions. Many attempts are being made by several organizations to reduce the greenhouse gas emissions from cars through the development of hybrid electric vehicles. For example, Nutley, NJ-based Hoffman-La Roche, Inc. (Roche), the U. S. prescription drug unit of the Roche Group, recently announced plans to integrate Toyota Prius and Ford Escape hybrid electric vehicles into its pharmaceutical sales fleet in an effort to help achieve the companys goal of reducing greenhouse gas emissions by 10 percent over the next five years. [6] To improve mileage: Automakers in the US need to meet Corporate Average Fuel Economy (CAFE) standards as required by law. At present, all new cars sold should be 27. 5mpg (8. 55 liters per 100km). [7] To overcome the shortcomings of an electric car: Electric cars have a short charge. They lacked the range (energy density of electric-vehicle batteries hovered around 70 to 100 watt-hours per kilogram, which automotive engineers called unacceptable) and the quick recharge time the auto industry said it needed. An example is seen in the case where GM introduced the EV1 in 1996. It had a top speed of 183 MPH, faster than any other production car out. It had a limiter that would not let it get above 85 MPH, because to drive the car at 183 MPH would deplete the batteries of their charge within 10 minutes. [8] Energy Consumption: Hybrid Electric Vehicles consume less energy than Internal-Combustion Engine (ICE) vehicles. [9] Why Are Hybrid Electric Vehicles A Better Choice? An important aspect of hybrid electric vehicles is that they make use of smaller engines. There are many advantages to this: Big engines are heavier than smaller ones so the car uses more energy anytime it accelerates or drives up a hill. The displacement of the cylinders is larger so each cylinder requires a greater volume of fuel. Bigger engines usually have more cylinders, and each cylinder uses fuel every time the engine fires, even if the car isnt moving. These are the reasons there is a difference in the mileage of two cars of the same model with different engines. If both cars are driving along the freeway at the same speed, the one with the smaller engine uses less energy. Both engines have to output the same amount of power to drive the car, but the small engine uses less power to drive itself. In a hybrid car, the gasoline engine can be much smaller than the one in a conventional car and thus can be more efficient. The engine in the hybrid car is powerful enough to move the car along on the freeway, but when it needs to get the car moving in a hurry, or go up a steep hill, it needs help. That help comes from the electric motor and battery this system steps in to provide the necessary extra power. The gas engine on a conventional car is sized for the peak power requirement (those few times when you floor the accelerator pedal). In fact, most drivers use the peak power of their engines less than one percent of the time. The hybrid car uses a much smaller engine, one that is sized closer to the average power requirement than to the peak power. Ways Hybrid Electric Vehicles Reduce Energy Consumption Besides a smaller, more efficient engine, todays hybrids use many other tricks to increase fuel efficiency. Some of those tricks will help any type of car get better mileage, and some only apply to a hybrid. To squeeze every last mile out of a gallon of gasoline, a hybrid car can: Recover energy and store it in the battery Whenever you step on the brake pedal in your car, you are removing energy from the car. The faster a car is going, the more kinetic energy it has. The brakes of a car remove this energy and dissipate it in the form of heat. A hybrid car can capture some of this energy and store it in the battery to use later. It does this by using regenerative braking. That is, instead of just using the brakes to stop the car, the electric motor that drives the hybrid can also slow the car. In this mode, the electric motor acts as a generator and charges the batteries while the car is slowing down. Sometimes shut off the engine A hybrid car does not need to rely on the gasoline engine all of the time because it has an alternate power source the electric motor and batteries. So the hybrid car can sometimes turn off the gasoline engine, for example when the vehicle is stopped at a red light. Figure 5. The frontal area profile of a small and large car Use advanced aerodynamics to reduce drag When you are driving on the freeway, most of the work your engine does goes into pushing the car through the air. This force is known as aerodynamic drag. This drag force can be reduced in a variety of ways. One sure way is to reduce the frontal area of the car (Figure 5). Think of how a big SUV has to push a much greater area through the air than a tiny sports car. Reducing disturbances around objects that stick out from the car or eliminating them altogether can also help to improve the aerodynamics. For example, covers over the wheel housings smooth the airflow and reduce drag. And sometimes, mirrors are replaced with small cameras. Use low-rolling resistance tires The tires on most cars are optimized to give a smooth ride, minimize noise, and provide good traction in a variety of weather conditions. But they are rarely optimized for efficiency. In fact, the tires cause a surprising amount of drag while you are driving. Hybrid cars use special tires that are both stiffer and inflated to a higher pressure than conventional tires. The result is that they cause about half the drag of regular tires. Use lightweight materials Reducing the overall weight of a car is one easy way to increase the mileage. A lighter vehicle uses less energy each time you accelerate or drive up a hill. Composite materials like carbon fiber or lightweight metals like aluminum and magnesium can be used to reduce weight. [10] Despite the advantages of hybrid vehicles, they are a middling choice whose future is far from assured. They are likely to be a victim of regulatory circumstance in the near term, pushed aside by improvements in gasoline emissions and by the Zero Emission Vehicles (ZEV) mandate which states that a specified percentage of manufacturers sales consist of ZEVs. [11] In the longer term, they will be squeezed between improving batteries and emerging fuel cells. If only fuel cells and advanced batteries falter, hybrid vehicles would have considerable promise and could play a central role in creating a more sustainable transportation system. Nissan Motor Company CEO Carlos Ghosn announced that he is unsure whether hybrid electric vehicles (HEVs) will remain competitive in the compact car market if the price of gasoline drops in the future. Speaking at a news conference in Tokyo, Ghosn acknowledged that Nissan will unveil a new HEV in 2006 as planned, but only to meet tightening emission regulations in California. Ghosn expressed doubt that U. S. benchmark crude prices would remain at current levels of $50 per barrel, which is fueling strong demand for HEVs. Reuters said Nissan instead plans to market its new fuel-efficient, gasoline-powered Tiida compact car to environmentally conscious drivers. [12] Disadvantages Of Hybrid Electric Vehicles By combining two propulsion systems and their associated energy storage units, they are inherently more complex than both pure battery-powered electric and pure internal-combustion vehicles.
